HOW THE FEMALE OF CACOECIA SEMIFERANA PROTECTS HER EGG-CLUSTERS.

Extract

The Box Elder Leafroller, Cacoecia semiferana, was very abundant in many places in Colorado last summer, and in July the moths were swarming in the trees in the evening, presumably to deposit their eggs. The eggs were found beneath a gluey mass, somewhat similar to that used by the tent caterpillar in protecting her eggs, but it was largely covered with what appeared to be scales from the moth, placed like the shingles on a roof.
